shell <command string> 调用UNIX的shell来执行<command string>,环境变量SHELL中定义的UNIX的shell将会被用来执行<command string>,如果SHELL没有定义,那就使用UNIX的标准shell:/bin/sh。(在Windows中使用Command.com或 cmd.exe) 还有一个gdb命令是make: make <make-args> 可以在gdb中执行make命令来重新build自己...
注意:若上述 print 命令出现 <optimized out>, 可能是因为 -O2 编译选项优化导致。 将makefile 里的 CFLAGS += -O2改成 CFLAGS += -O0 重新编译再调试即可。 catchpoint 从字面意思理解,是捕获断点,其主要监测信号的产生。例如c++的throw,或者加载库的时候,产生断点行为。 ❝在command命令后加断点编号,可以...

<qemu:commandline> <qemu:arg value='-s'/> </qemu:commandline> </domain> 所以这时运行在虚拟机里的内核已经可以被调试了。 调试内核 在宿主机上运行gdb需要内核的二进制文件,这个文件就是在虚拟机GRUB里配置的/boot/vmlinuz-5.4.106。为了方便在调试过程中查看源代码,我们可以将虚拟机的/usr/src/linux-...

If you try using the disassemble command to disassemble code outside any known function, it will fail. Instead use the x/i command. Here's an example of disassembling a buffer containing a copy of a function:(gdb) start Temporary breakpoint 1 at 0x8048463: file test2.c, line 8. ...
